fire

Today, an urgent problem in modern construction is the development of highly functional fire-resistant solutions to protect the timber from destruction and the effect of fire on it, which are characterized by the high efficiency of the penetration of these solutions into the middle of the timber, the durability of their protection and operational properties to ensure the longevity of the operation of timber structures. One of these fire-resistant solutions is a solution invented on the basis of the method of impregnation of timber based on area.

The present standards do not consider cases for timber elements covered with fireresistant penetrating coatings and jointed claddings simultaneously. This article is focused on the influence of such combined fire protection on charring depth of studs in timber frame wall assemblies exposed to fire. A key idea was to investigate rather common in local building types of wall assemblies. Wood panels with rabbet joints as cladding with commercially available fire-coating were used for the frame specimens with loose-fill mineral wool filling.

The materials of the article the radial heat flow, which is present in a fire, and analyzed factors flame from which the heat flow is dependent. Based on experimental studies installing dependence heat flux changes with distance, and the influence of environmental parameters in which the radial heat transfer on the intensity of radiation energy flame. Based on the studies identified and specified coefficient weakening energy radiation flame small water spray.

Development of fires in residential buildings is usually accompanied by the release of hot gases through the openings in walls. Along with the hot gases through the openings may come and plume flame, which increases radiating component of heat flow from the openings. The paper experimentally investigated at the time of the fire change size and shape of the plume flame, which goes through the openings enclosing constructions.

In the paper are presented the results of diagnostics, tests of materials, numerical modelling and static analysis of the current state of the bearing steel structure of the hall after a fire and design of the actions for the repair of the damaged steel structural members.

his paper is the results of the experiment to study the dynamics of fire in the premises of residential buildings on models size reduction and improvement of methods for determining the temperature conditions of movement of gases and warming their structural elements using markers and thermal imager. The tests on models of small-scale examination demonstrated the dynamics of fires in residential areas and make for verification of the data model based on fires CFD.
